Spherical netted shell combined structure

Abstract

A bridge structure includes three concentric spheres composed by chords. The upper and lower spheres are jointed by web members to form a double layer net shell. Over the upper sphere, install the top sphere via web members. Steel bars are connected to the node of each hexagon of the upper sphere, and bottom mold is installed to the bottom of the upper sphere.

Description

technical field The invention belongs to a bridge structure, and mainly relates to a bridge with a large-span concentric spherical reticulated shell structure. Background technique At present, beam bridges, arch bridges, cable-stayed bridges and cable bridges are commonly used in bridge construction. Due to the difficulty in solving the stress problem in the design of bridge structures, girder bridges, arch bridges and cable-stayed bridges can only be designed and constructed with the support of bridge piers. The cost is greatly increased; the span of a cable bridge is larger than that of a girder bridge, an arch bridge, and a cable-stayed bridge, but since the height of the towers at both ends of the cable bridge is proportional to the length of the bridge, the length of the cable bridge should not be too large. Contents of the invention The purpose of the present invention is to solve the problems existing in the above-mentioned prior art, and to design and provide a ...
